Description

technical field

[0001] The invention relates to the technical field of mechanical equipment, in particular to a dust-proof hand electric drill. Background technique

[0002] Electric hand drill is a drilling tool powered by AC power supply or DC battery. It is a kind of hand-held electric tool. For making holes in objects or piercing objects, some industries are also called electric hammers. The main components of electric hand drills are: drill chucks, output shafts, gears, rotors, stators, casings, switches and cables. The following disadvantages still exist in actual use:

[0003] 1. Existing electric hand drills will generate a lot of dust during use, which is inconvenient to use without protective measures and is highly restrictive;

[0004] 2. The dust generated during the use of the electric hand drill may contain a large amount of toxic substances. When the electric hand drill is used for a long time, the human body will inhale the dust and the health will decline;...
